# Conventions
## Language & Dependencies
- Target the latest stable Go release.
- **STRICT ALLOWLIST:** Only packages listed below may be imported. No exceptions.
### Approved Third-Party Packages
| Package | Use Case | Scope |
|---------|----------|-------|
| `github.com/goccy/go-yaml` | YAML parsing (persona files, config) | production |
| `github.com/google/go-cmp` | Test comparisons (`cmp.Diff`) | test only |
**Any import not in this table or the Go standard library is forbidden.**
Transitive dependencies of approved packages are automatically allowed.
To request a new dependency:
1. Open a PR that ONLY updates this table
2. Requires explicit approval from Aaron
3. After merge, a separate PR may use the package
*Enforcement: `scripts/check-deps.sh` parses this table — update only here.*
## Error Handling
- Return errors; never panic.
- Wrap errors with context using `fmt.Errorf("context: %w", err)`.
- Check all error returns.
## Testing
- Test every exported function.
- Use `net/http/httptest` for HTTP mocking.
- Table-driven tests where multiple inputs share the same assertion logic.
- Integration tests use build tags (`//go:build integration`).
## Style
- Keep functions short and focused.
- Prefer early returns over deep nesting.
- Meaningful variable names — no single-letter names outside loop indices.
- Comments explain *why*, not *what*.
## Process
- `go test ./...` must pass before commit.
- `go vet ./...` must pass before commit.
- Keep commits atomic and well-described.
